RESULTS: There were all three types of PPARs mRNA expression in HUVECs, while the expression of PPAR? was less than that of PPAR?( P

Objective:To explore clinical significance of sinus heart rate turbulence (HRT) phenomenon in aged pa‐tients with stable angina pectoris (SAP) .Methods :A total of 120 aged SAP patients ,who received 24h DCG in our hospital from Jan 2013 to Oct 2015 ,were selected as SAP group .Meanwhile ,another 144 aged patients ,who re‐ceived 24h DCG examination simultaneously and coronary angiography results were normal ,were regarded as nor‐mal control group .According to coronary lesion severity ,SAP group was further divided into single vessel coronary disease group (single vessel group ,n=35) ,double‐vessel coronary disease group (double‐vessel group ,n=48) and multi‐vessel coronary disease group (multi‐vessel group ,n=37) .The 24h DCG ,HRT indexes ,including turbulence onset (TO) and turbulence slope (TS) ,were measured and compared among all groups .Results:Compared with normal control group ,there was significant rise in TO [(0.77 ± 0.37)% vs .(1.26 ± 0.92)% ] and significant reduc‐tion in TS [(5.45 ± 4.02) ms/RR interval vs .(1.53 ± 0.70) ms/RR interval] ,P<0.01 both ;significant rise in ab‐normal rates of TO (19.44% vs .42.50% ) ,TS (15.97% vs .31.67% ) and TO + TS (11.11% vs .30.83% ) in SAP group ,P<0.01 all .Compared with single vessel group ,there was significant rise in TO [(0.66 ± 0.22)% vs .(1.28 ± 1.11)% vs .(1.46 ± 1.20)% ] and significant reduction in TS [ (2.04 ± 0.82) ms/RR interval vs .(1.66 ± 0.38) ms/RR interval vs .(1.29 ± 0.58) ms/RR interval] in double‐vessel group and multi‐vessel group ,and TO of multi‐vessel group was significantly higher than that of double‐vessel group ,TS of multi‐vessel group was significantly low‐er than that of double‐vessel group , P<0.01 all .Conclusion:Sinus heart rate turbulence can be used as risk predic‐tor for aged patients with stable angina pectoris ,which can provide basis for clinical effective treatment and progno‐sis assessment .

[Objective] To investigate the mesenchymal stem cells (MSC) in treating acute lung injury (ALI) via ALI mouse model.[Methods] By monoclonal antibody Anti-GD2 of specific antigen ganglioside (GD2) only expressed on MSC as a carrier,new fluorescent molecule probe were synthesized through covalently coupling Anti-GD2 and fluorescent group CyDye mono-reactive NHS Esters (Cy7).Synthetic Anti-GD2-Cy7 and MSC were labeled by the specific binding of antigen and antibody in vitro.Total 84 balb/c male mice were selected and randomly selected 48 mice were divided into three groups:sham group (n =16),MSC+ ALI group (n =16),NS + ALI group (n =16).The lung histopathology and scores,lung W/D ratio and permeability of lung microvasculature were examined at 24 h,48 h after ALI mouse model.Other 36 mice were randomly divided into three groups:normal group (n =12),sham group(n =12),MSC +ALI group(n =12).Labeled MSC-GD2-Cy7 were transplanted into MSC+ALI group and sham group mice via tail vein injection.At 30 min,1 d,3 d,and 7 d post-MSC-GD2-Cy7 injection,the mice were sacrificed after anesthesia and then the lung was removed.Excised lung was detected on small animal fluorescent imager.[Results] Contrast to NS+ ALI group,the lung histopathology and scores,lung W/D ratio and permeability of lung microvasculature of MSC +ALI group were more greatly improved at both 24 h and 48 h.Fluorescent results showed that the signal intensity in thc lung of MSC +ALI group was significantly higher than that of sham group at each time point [(3.37 ± 0.02)× 10-4 vs (2.05 ± 0.04) × 10-4 scaled counts/s;(35.54 ± 0.47)× 10-4 vs (25.29 ± 1.48) × 10-4 scaled counts/s;(11.17 ± 0.75)×10-4 vs (6.09 ± 0.62)× 10-4 scaled counts/s;(3.10 ± 0.14) vs (0.00 ± 0.00)× 10-4 scaled counts/s;all P ＜ 0.05].[Conclusion] Our study showed that a proportion of cells migrated into normal and injured lungs 30 min after cell transplantation,and the cells started to recruit and largely gather in injured lungs at day 1 and persisted to day 7,these results suggest that MSC possess the ability to home into injured tissues.

Objective To explore the role of MKK34 (a peptide spanning a C-terminal α-helical region in TSLP) on airway inflammation and β-catenin of airway epithelium in a HDM-induced mouse asthma.Methods 32 male BALB/c mice were randomly divided into control,MKK34,asthma and MKK34 + HDM groups.The mice in the asthma group were exposed to HDM for five consecutive days and the MKK34 + HDM group was pretreated with MKK34 1 h prior to the HDM intranasally treated.After 8 weeks' treatment,animal lung function test and pathological staining were performed to evaluate the asthma situation,IL-4,IFN-γin bronchoalveolar lavage fluid and IgE in the serum were detected,immunohistochemistry and western blot were used to assess β-catenin and p-ERK,t-ERK levels.Results Airway reactivity,IL-4 and IgE in the asthma group were significantly higher than that in the control group.Treatment with MKK34 significantly decreased airway hyperresponsiveness,IL-4 and IgE.HE staining demonstrated the chronic bronchitic inflammation in the lungs of asthma group.β-catenin in the control group was distributed evenly at the cytomembrane of epithelial cells.In the asthma group,β-catenin was disordered in epithelial cells and its expression was decreased.Treatment with MKK34 ameliorated the damage of β-catenin and chronic bronchitic inflammation.The protein levels of p-ERK1/2 increased obviously in the asthma group.The pretreated group significantly decreased the expression of p-ERK1/2.Conclusions MKK34 can ameliorate the airway inflammation and the destruction of β-catenin of airway epithelium in a HDM-induced mouse asthma.The ERK pathway may play a role in this process.

Objective To investigate the application effect of nasojejunal feeding tube nutrition in patients with severe traumatic brain injury. Methods The clinical data of 54 patients with severe traumatic brain injury admitted to the Department of Surgical Critical Care Medicine,the Third Affiliated Hospital,Sun Yatsen University between June 2012 and December 2014 were analyzed retrospectively. They were divided into either a nasojejunal feeding tube nutrition support group (nasojejunal group,n = 26)or an asogastric feeding tube nutrition support group (asogastric group,n = 28)according to the different ways of enteral nutrition. All patients began to receive nasal feeding whole protein preparations (enteral nutritional emulsion,TPF-D)from the second day after admission to intensive care unit (ICU). The time to reach the enteral nutrition support target,the time of parenteral nutritional support,nutritional index (albumin and hemoglobin),the time admission to ICU,and the incidences of infection and gastrointestinal complications in both groups were observed. Results (1)According to the body weight to calculate calorie demand, the nasojejunal group reaching the time of enteral nutrition support target was faster than that of the asogastric group (3. 0 ± 0. 8 d vs. 7. 7 ± 2. 5 d). There was significant difference between the 2 groups (P < 0. 01). The time of the combined parenteral nutrition support in the nasojejunal group was reduced significantly compared with the asogastric group (2. 0 ±0. 8 d vs. 6. 7 ±2. 5 d). There was significant difference between the 2 groups (P <0. 01). (2)At day 30after treatment,the levels of total serum protein and hemoglobin in the nasojejunal group were higher than those of the asogastric group (64 ± 6 g/ L vs. 61 ± 6 g/ L and 120 ± 17 g/ L vs. 106 ± 16 g/ L,respectively. There were significant differences (P < 0. 05). (3)The mean length of stay in the ICU was obviously shorter in nasojejunal group compared with the asogastric group (11 ± 5 d vs. 14 ± 6 d). There was significant difference between the 2 groups (P < 0. 05). (4)There were no significant differences in complications of the patients,such as the incidences of pulmonary infection,hyperglycemia,and diarrhea between the 2 groups (P > 0. 05). Conclusion Nasojejunal feeding tube nutrition support may be faster to achieve the target of enteral nutrition supports and shorten the time in ICU.

OBJECTIVETo evaluate the effect of 25-hydroxyvitamin D(3) on the expression and distribution of vitamin D receptor in normal human bronchial epithelial cells.

METHODSMTT assay was used to assess the viability of human airway epithelial cell line 16HBE following a 24-h exposure to different concentrations of 25-hydroxyvitamin D(3). Real-time quantitative PCR, Western blotting, and immunofluorescence assay were used to observe the expression and distribution of vitamin D receptor in the cells following the exposure.

RESULTSCompared with the control cells, 16HBE cells exposed to different concentrations of 25-hydroxyvitamin D(3) exhibited no significantly increase in the expression or distribution of vitamin D receptor.

CONCLUSIONThe influence of 25-hydroxyvitamin D(3) on bronchial epithelial cells might be independent of the expression and translocation of vitamin D receptor.
